Over the years using the modular i have a common monosynth patch up i regularly use in my music , my idea is to build a hardwired synth using those modules from the main system and house them on a new panel & wooden box , thus freeing up space for more modules in the blue wardrobe.

I sketched out the design of plywood box to fit in the small space under the ASM-2 synth, then into the shed armed with saw , measuring tape , set square & straight edge & pencil ,pva wood glue , bag of 1" brads / panel pins & hammer. Oh , and nice plywood off cuts from a work skip .

After a couple of swearing incidents and a tea break and this is what i hacked together today.

Here is my first draught of my layout for the front panel , i've got it to fit to 250mm high by 500mm wide on 3mm aluminium sheet , leaving a single module space to the right when the panel fits to the box , which is 603mm long inside.

Most of the parts of this synth will come from my main modular , so it's mainly a re- panel / re-wire job with a few extra pcbs to build in the modulation area.

To fill the space on the top right im thinking of using an multi-FX pedal and a distortion / overdrive with ken stone stompbox circuits on veroboard.

I'm going to let this layout simmer for a few weeks until i get an offcut of alum panel from a metal fabricator/engineers workshop.

i've spent a few days with the modulation sources for all the CV attenuators , making sure they are evened out over the destinations, i hope i've covered all my usual patch configurations with this layout

Hi ,
The 6 lfo's i have made on veroboard are from Ray's site under the oldies but goodies section , six of the "variable skew lfo" which outputs 3 main waves... sine / ramp - tri - saw (skew) / square.

I have made a few veroboard circuits and i now just follow the diagram and populate and isolate as i go and give it a good continuity test afterwards before the "no chip" power up test.

I have also started to the mfos micro S & H circuit which will have the lockhart wave folder & dividers on the same strip.

What filters are you going to use? I like a variation from the standard LPF. A SVF or a combined LP/HP such as the MOTM CS80, Ian Fritz Threeler? I have a CGS CMOS or Wasp style filter on the drawing board. Mine will have dual-concentric pots to control two filters from one(ish) set of controls. I got these from Small Bear._________________http://soundcloud.com/for-mash-get-ash

I have a mfos lowpass for vcf1 and a mfos state variable for vcf2 that are to be taken from the modular .

cool , dual pots is a good idea , hope to see pics of your twin vcf your building / planning.

On my filter section, im going for a toggle switch to choose between normal independant vcf CV control or vcf1 CV in sum to vcf2 cv in, so they can both be sweeped from vcf1 cutoff dial. (whooooosh! sounds and more )

Im slowly taking my time with this build , heh , ive rearranged the panel layout a bit to fit the FX i wanted on the panel, which is now 600mm long , still in the final stage of "what can i put in that space" , i was thinking vc-panner or a externally clocked melodic/random trigger generator of some sort for the 4 ADSR's. Hmmm.

This is just a screen shot of my Shaeffer design. On the left is the Wasp filter. The small circles are for the dual-concentric knobs, below switches for filter type then the banana sockets. I colour co-ordinate; blue for in and yellow for out so I dont need to add any labels. The small and larger circles are to show which part of the control is for which or the 2 filters. I try to eliminate writing and use signs and colours to define functions. I need to work on some graphic icons to add to the layout to reduce the writing even more. Something as corny as a graphic for an envelope of an envelope!!

Mad idea.... ignore this if you have finalised the design...... a double pole switch to swap one of the filters sweep direction on the dual pot , half way turn on the dual pot would be the cross-over point of the 2 filters sweeps.

I was scanning over the layout and it dawned on me i'd forgotten glide/ portamento on the vco's , fixed now , i've considered a few circuits for the space at the right end of the panel and i think im drawn to ken stones burst generator circuit for a bit of spicey trigger action on the ADSR's & probly through an attenuator to the vco cv in's as well.

Finish the panel design , then off to the print shop up town for a black n white drill template sticker and the finishing final 250mm x 600mm lilac / purple vinyl sticker with black text lazered on.
